Perfect! I love the way you make use of the "Unkiss" and their past: all the references to the battle of the Blackwater, to Alayne Stone or to the Quiet Isle make this story so real. I love all those tiny details too: Stranger nudging at her back, for example, is so funny.
I've just realized something about this pairing. Sansa's love for Sandor seems impossible, but you give us the best explanation: he makes her feel alive. That's it.
I can't wait for your next post!
